Novel electrolysis device

The invention discloses a novel electrolysis device. The novel electrolysis device mainly comprises a tank body, a rotating device, a rotating powered device, an electrolysis power source and a polarity changing power source, wherein one cathode roller is arranged at each of the two ends in the tank body; a cathode plate strip sleeves the two cathode rollers; anode plates are parallelly placed on the side surfaces of the cathode plate strip; anode conductive bars connected with the anode plates are connected with the anode of the electrolysis power source; the two ends of one of the two cathode rollers are separately connected with the rotating device and the rotating powered device; the rotating powered device is connected with the cathode of the electrolysis power source, is connected with the anode of the polarity changing power source, and is provided with a change-over switch used for switching a current loop; and polarity changing semicircular arc plates connected with the cathode of the polarity changing power source are arranged on the outer edges of the cathode rollers. The novel electrolysis device has the advantages that automatic cleaning is achieved, the cathodes do not scale, electrolytic efficiency is high, pickling facilities are not required, damage of pickling to the polar plates is eliminated, the anodes are not subjected to polarity changing, and service life of the anode plates is prolonged.
